Abstract
This thesis examines cursor nudging, a subtle form of digital nudging that influences user decisions through cursor movements and visual cues, with the goal of understanding its impact on behavior and its applicability to clinical decision support. Two complementary studies were conducted. Study 1 was an online, controlled web application with 35 general users who experienced four nudge types (Border, Crawl, Pointer, Shape); it collected primarily quantitative ratings of effectiveness and user experience. Participants reported a generally positive reception, with the visual Shape nudge rated highest for both impact and satisfaction. Many felt guided by the nudges while highlighting tensions between guidance and a sense of control. Study 2 focused on the clinical domain and qualitatively evaluated the Border nudge with medical professionals making diagnostic decisions. Clinicians reported that the nudge could help manage extensive medical knowledge, reduce cognitive load, make choices more deliberate, and save time, while also raising concerns about potential over-reliance on AI and the need for transparency. Overall, the findings suggest cursor nudging can enhance decision-making in both general and clinical contexts when implemented ethically and transparently, though limitations include small samples and short-term assessment; future work should involve larger, more diverse cohorts and investigate long-term effects.
Denne afhandling undersøger cursor nudging, en subtil form for digital nudging, der påvirker brugerbeslutninger via markørbevægelser og visuelle signaler. Formålet er at vurdere, hvordan forskellige nudges påvirker adfærd og beslutningstagning i almindelige digitale opgaver og i kliniske beslutningsstøttesystemer. To studier blev gennemført. Studie 1 var en online undersøgelse med 35 deltagere, der brugte en kontrolleret webapplikation og oplevede fire nudgetyper (Border, Crawl, Pointer, Shape). Undersøgelsen indsamlede primært kvantitative vurderinger af effektivitet og brugeroplevelse. Deltagerne havde generelt en positiv holdning til cursor nudging, og den visuelle Shape-nudge blev vurderet højest for både effekt og tilfredshed. Flere beskrev, at nudges guidede dem, samtidig med at spørgsmål om balancen mellem vejledning og kontrol blev tydelige. Studie 2 fokuserede på klinisk brug og involverede sundhedsprofessionelle i en kvalitativ evaluering af Border-nudgen i diagnostiske beslutninger. Deltagerne rapporterede, at nudgen kunne støtte håndtering af omfattende medicinsk viden, reducere kognitiv belastning og gøre valg mere overvejede, samt spare tid, men de udtrykte også bekymringer om potentiel overafhængighed af AI og behovet for gennemsigtighed. Samlet set peger resultaterne på, at cursor nudging kan forbedre beslutningstagning i både generelle og kliniske sammenhænge, forudsat at etiske hensyn og brugeraccept prioriteres. Begrænsninger omfatter små stikprøver og fokus på kortsigtede effekter; fremtidigt arbejde bør omfatte større og mere mangfoldige deltagergrupper samt undersøge langtidseffekter.
